TELEPHONIC ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 546,972, dated September 24, 1895.

Application filed January 14, 1895. Serial No. 534,740i (No model.)

To aZZ whom it may concern.-

Be it known that I, LOUIS JAY GERSON, of the city and county of Philadelphia, State of Pennsylvania,have invented an Improvement in Telephonic Attachments, of which the following is a specification.

Myinventiou relates to attachments for telephones; and it consists of certain improvements which are fully set forth in the following specification, and are shown in the accompanying drawings.

More particularly myinvention is a speaking attachment to be applied to the transmitters of telephone instruments, and is designed to enable 'the person using the instrument to move the speaking-tube into any position desired to suit his height or the position in which he may be standing.

It is also an object of my invention to accomplish this result while preserving a straight open passage for the Voice through the tube upon the vibrating plate of the transmitter, so that the transmission of the vibrations is in no way obstructed by the adjustment of the tube.

In carrying out my invention I employ a suitable frame adapted to be attached to the box of the transmitter, with a speaking-tube connected therewith by a universal joint.

Referring to the accompanying drawings, Figure 1 is a perspective view of a telephone having my improved attachment applied. Fig. 2 is an enlarged longitudinal sectional view of my improved attachment. Fig. 3 is a perspective view of the same; and Fig. 4 is a perspective View of the detached tube, illustrating a modification.

The attachment consists of a frame A, adapted to be clamped or otherwise attached to the transmitter, and a tube B connected with the frame Aby a universal joint, whereby the tube may be turned in any desired direction to suit the elevation or position of the mouth of the person using the instrument.

My preferred construction of the universal joint consists of a ball and socket O, as shown in the drawings.

The frame A is constructed with an aperture D, adapted to occupy a position over the mouthpiece of the transmitter, adjacent to which is a ball-shaped socket adapted to re ceive the ball-shaped end of the tube A.

The ball-shaped socket is preferably constructed of flangesE F, extending from the inner and outer faces, respectively, and properly curved to form the ball-socket, open at its inner side, to the mouthpiece of the transmitter, and at its outer side to receive the tube and permit the desired movements.

The tube B is shown provided with an enlarged ball-shaped end G, adapted to fit within the socket formed by the flanges E F, and to turn freely therein. The inner end of the tube is open to the mouthpiece of the transmitter. The outer endof the tube Bis shown provided with a suitable flaring mouthpiece H. WVith the tube B connected with the frame A in this manner it is possible, while permitting the tube to be turned in any desired direction, to preserve a straight open line from the mouthpiece I-I directly upon the vibratory plate of the transmitter. The tube may be easily turned in any direction, either up or down, to suit the height of the person speaking, or to the right or left to suit convenience or position of the instrument. In whatever position the tube may be turned the voice will be thrown directly upon the transmitter. The tube B may be made in telescoping or sliding sections, as shown in Fig. 4, so that it may be lengthened or shortened when desired. The frame A may be secured to the transmitterboX in any desired manner. I have shown it provided with flanged clamping edges I, adapted to engage the rim of the boX.

These and other details of construction may be varied without departing from the invention.

That I claim as new, and desire to secure by Letters Patent, is-

1. A speaking attachment for telephones, consisting of an attaching frame, and a speaking tube connected therewith by a ball and socket joint, whereby the tube may be turned in any direction.

2. A speaking attachment for telephones, consisting of an attaching frame A having an aperture D, and a ball shaped socket about the aperture, and a tube 13 having an open adapted to fitthe ball shaped socket composed balishaped end Gadaptedto fit theball shaped of the flanges E, F. IO socket of the frame A. In testimonyof which invention Ihavehere- 3. A speaking attachment for telephones, unto set my hand. consisting of an attaching frame A having an LOUIS JAY GERSON. aperture D and. flanges E, F, in the inner and Witnesses: outer faces respectively forming a ball shaped ERNEST HOWARD HUNTER,

socket, and the tube B having the ball end G VVM. L. EVANS.
